Want a perfectly flushed complexion? You need a great blush. Here are the ones that'll help you glow -- and the ones that are so bad they'll turn your cheeks red with frustration

Why: Readers give an "oh no" to this product. Unfortunately, "the color seems to be the same on any and every skin tone," leaving readers to "doubt that this blush reacts differently to different skin tones" like the product claims. "It was really difficult to control how much color you wanted," says one reader. "The hardest part was getting both cheeks evenly colored." Reviewers also said it's "not a good product for oily or combination skin," it "doesn't really have staying power" and "made [them] break out."
